link aggregation Alcatel switches

not sure if this question should be asked in this area, but feel free to move it if it shouldn't.

So, I have 3 Alcatel switches in stack mode and I am trying to connect them with a pfsense appliance XG-1541. The cxI0 an cxI1 ports have been configurred as lagg ports.

From each of these ports I have an 10gig sfp copper cable connected to a corresponding port in my Alcatel switch.

Unfortunately I haven't succeded in passing any traffic through these ports and this is why I am starting this topic. Does anyone know what kind of configuration I should have in my alcatel switch? I am configuring it both as static and dynamic lagg on my alcatel but I am not able to ping any address behind the switch.

I believe the first screenshot is pretty much the same as what you posted. And yes, I’ve set LACP.

I believe the aggregate works but somehow I have an issue in routing. And this is because I’ve put the pfsense running side by side with my old checkpoint firewall (I have to let them work side by side for a while)
